Magnetic Construction Toy

ABSTRACT

A construction toy is provided, with illustrated panels that connect together magnetically to assemble two- and three-dimensional structures and background scenery, optionally with accessory items that bind magnetically or mechanically to the panels to embellish the structures or scenes that are created.

FIELD OF THE INVENTION

The invention relates to a construction toy, in particular a toy thatincludes illustrated panels that connect magnetically at their edges toconstruct structures or scenes.

BACKGROUND

Construction toys, or building sets, have long provided children witheducationally enriching play. Through the act of building, kids developfoundational science, technology, engineering and math (STEM) skillssuch as spatial reasoning and decision making Magnetic construction toyssuch as Magformers®, Tegu®, and Magna-Tiles® have made building moreaccessible to children by having pieces that join magnetically withoutthe need for precise dexterity that is often required when assemblingwith plastic building bricks such as Lego® or even plain wooden blocksthat can easily topple. These existing magnetic construction toys arecomposed of abstract plastic or wood shapes (panels) that can becombined magnetically to form a larger structure.

Existing panel type magnetic building sets do a good job in getting kidsto build structures, but they fall short in the opportunity to createlong-term engagement by involving children in narrative development. Thestructures that are formed are abstract, which makes it difficult formany children to engage in imaginative play with the structures.Contrast this to Lego®, which has had much success in theming their onceexclusively abstract plastic bricks, allowing children to act out andembellish upon stories implied by the themes. The approach to combinestructural and narrative building is especially important to interestgirls, who have historically been underserved in the construction toycategory.

GeoMag® has made a few attempts with themed magnetic building sets, butthese sets are cumbersome to play with as there are many small partsrequired for assembly since the magnets are separate pieces rather thanbeing housed within the shapes/panels.

In addition to a deficiency in providing thematic backdrops forimaginative play, existing magnetic construction toys present a numberof challenges for getting building pieces to magnetically attractregardless of orientation. For example, some magnetic building toys havea set orientation dictated by magnetic polarity (see, e.g., PCTApplication No. WO 2010111189 A1), which limits the way the child cancombine panels. Others use magnets that spin around or roll to attractthe magnets in a neighboring panel (see, e.g., U.S. Pat. No. 7,160,170B2 and Japanese patent publication nos. 2003-190663 and 06-302425). Thisallows for panels to connect regardless of orientation but requiresexpensive Neodynium magnets, which also pose a safety risk to childrendue to their strength. Other building sets separate the magnets from thepanels so that the shapes don't have a set magnetic polarity (see, e.g.,U.S. Publication No. 2007/0287353). This works to provide the child withfreedom of choice but creates an inconvenience with additional smallparts to keep track of as well as posing a choking and swallow hazard.

There is a need for an improved magnetic construction toy that providesillustrated, thematic backdrops for imaginative play and in whichmagnetic panels may be assembled and re-assembled with ease and withoutsmall pieces that could present a choking hazard to small children.

BRIEF SUMMARY OF THE INVENTION

Construction toys are disclosed herein that encourage building andimaginative play via illustrated panels that connect magnetically toform a larger structure or scene. The panel illustrations providejumping off points for storytelling and imaginative play. The panelsconnect regardless of orientation, providing the child with freedom ofchoice to combine the panels in any way they choose. The magnets arehoused within the edge(s) of each panel, so that no separate smallmagnet connectors are required. Magnetic accessory items can optionallybe added to the face(s) of panels to further customize and embellish thescene. The freedom of configuration and the optional magnetic accessoryitems increase replayability as children modify the story context andexperiment with different designs, providing endless opportunities forimaginative play.

Illustrated Panels

The construction toys described herein contain a plurality of panelswhich may be combined to form three dimensional structures, such ashouses, buildings, enclosures, etc., or backdrop scenery, forimaginative play. A plurality of panels of a construction toy, asdescribed herein, refers to two or more panels and typically refers to anumber of panels that is sufficient for the user to construct athree-dimensional structure and/or scenery backdrop for imaginativeplay.

Each panel contains at least two faces, typically parallel orsubstantially parallel to each other, and at least three edges. Thefaces are in the form of polygon shapes, such as triangles, squares,rectangles, pentagons, etc. Each panel contains two faces of the samepolygon shape and of the same or substantially the same dimensions, andeach side of the polygon forms an edge of the panel (e.g., three edgesfor a triangular panel, four edges for a square or rectangular panel,etc.). The edges are perpendicular or substantially perpendicular to thefaces. Each edge has a depth suitable to contain one or more embeddedmagnet(s), as described herein.

At least one (i.e., one or more than one) panel of the construction toycontains an illustration on at least one face. In some embodiments, atleast one panel contains illustrations on both faces. In someembodiments, several panels (i.e., more than one), a majority of panels,or all panels contain illustrations on at least one face. In someembodiments, at least one panel, several panels, a majority of panels,or all panels contain illustrations on both faces.

An “illustration” (e.g., an illustration on an illustrated face of apanel of a construction toy as described herein) refers to an image ordepiction, including but not limited to, a drawing, sketch, painting,photograph, engraving, etching, or embossing, of things seen,remembered, or imagined, using a graphic or tactile representation. Theillustrations may be in the form of pictures or scenery, for example, aninterior or exterior floor, wall, or roof of a building or otherstructure, or rural, urban, or natural exterior scenes. Illustrationsmay be printed, engraved, etched, or embossed on the exterior face of apanel, or may be created by a user directly on the face of a panel oraffixed to the face. Exemplary, nonlimiting materials which may be usedfor the exterior, illustrated surface of a face of a panel include wood,plastic, magnetic receptive material, magnetic material, cardboard, etc.

Each panel contains at least one magnetic edge. A magnetic edge refersto an edge of a panel that contains tat least one magnet embedded withinthe panel and in proximity to the edge, and configured to magneticallyattract a magnetic edge of another panel. In some embodiments, all edgesof a panel are magnetic. Panels may be connected by magnetic attractionbetween their respective magnetic edges to construct structures orillustrated backdrops and/or scenery. In some embodiments, panels areconnected with magnetic edges parallel (180° angle). In anotherembodiment, panels are connected with magnetic edges perpendicular (90°angle). In other embodiments, panels are connected at their magneticedges at an acute or obtuse angle.

In some embodiments, panels may be connected magnetically at adjacentedges to form a contiguous illustrated scene, such as a rural scene,cityscape, or natural landscape.

In some embodiments, panels may be connected magnetically at theirmagnetic edges to form a three dimensional structure, such as a house,building, or other enclosure, with illustrated interior and/or exteriorwalls, floors, and/or ceilings/roofs, and optionally associated outdoorscenery. This is shown schematically in FIG. 1.

FIG. 1 shows panels with illustrated faces (e.g., 1, 4) connected atmagnetic edges (e.g., 2, 3). Panels may be connected, for example, in athree-dimensional configuration (5) (e.g., perpendicular magnetic edges)or side-by-side (6) (e.g., parallel magnetic edges), or at other angles.Structures (e.g., 5) and/or scenery or enhancements to structures (e.g.,1, 4) may be constructed.

In some embodiments, illustrations are designed such that panels may berearranged in sequence and/or orientation to form different structuresand/or scenery from the same set of panels.

Construction toys as described herein may contain panels of the samesize and shape or of different sizes and/or shapes. (See, e.g., FIGS. 1and 7.) In some embodiments, adjacent panels in a structure or scenehave edges of the same length, such that they magnetically connect alongthe entire lengths of the adjacent magnetic edges (e.g., 22 and 23 inFIG. 7). In some embodiments, adjacent panels in a structure or scenehave edges of different lengths and the shorter magnetic edge of onepanel (e.g., 25 or 26 in FIG. 7) magnetically connects along a portionof the length of the longer magnetic edge of the other panel (e.g., 24in FIG. 7).

A panel face may optionally contain a material on at least a portion ofits exterior surface, or interior to at least a portion of the face ofthe panel, configured to magnetically attract one or more accessoryitem(s) to the exterior surface of the panel, to embellish theillustration depicted on the panel or depicted in a combination ofpanels that are constructed to form an illustrated structure or scene.In some embodiments, a panel face may contain an interior or exteriormagnetic receptive material, which may attract a magnetic surface of anaccessory item. In other embodiments, a panel face may contain aninterior or exterior magnetic material, which may attract a magneticallyreceptive surface of an accessory item. In other embodiments, a panelface may contain both magnetic and magnetically receptive materials indifferent interior and/or exterior areas of the panel face. “Magneticreceptive material” refers to a material that attracts a magneticmaterial but is not itself permanently magnetic. In various embodimentsof panels and/or accessories described herein, magnetic receptivematerial may include, but is not limited to, rolled steel, a steel plateor grid, or a flexible magnetic roll product, such as FlexIron™,FlexMag™ or RubberSteel®.

In one embodiment, at least a portion of the exterior surface of a panelface includes a magnetic receptive material. In another embodiment, atleast a portion of the exterior surface of a panel face includes amagnetic material. In a further embodiment, at least a portion of theexterior surface of a panel face includes a magnetic receptive materialand at least a portion of the exterior surface of the face also includesa magnetic material. In a still further embodiment, the exterior surfaceof the panel face is constructed of a material that is not magnetic ormagnetic receptive, and magnetic and/or magnetic receptive material(s)are interior to the panel face but configured such that they are capableof magnetically attracting magnetic receptive and/or magnetic materials,respectively, to the exterior surface of the panel face.

In some embodiments, a panel is constructed with a substructure thatincludes at least one magnetic edge (i.e., at least one or more embeddedmagnet(s) as described herein). A “substructure” is interior to thepanel surface, and is the same or substantially the same shape as thefinished panel. A substructure contains two faces and the same number ofedges as the finished panel, and at least one edge of the substructurecontains one or more embedded magnet(s). Generally, the lengths of theedges are in the same or substantially the same proportions as thefinished panel. One or more materials may cover the face(s) and/oredge(s) of the substructure to produce the finished panel. In someembodiments, the substructure may be constructed of plastic, wood, foam,cardboard, or a combination thereof, or other suitable materials knownto those of skill in the art.

In some embodiments, depicted schematically in FIG. 9, a panel isconstructed with at least one magnetic receptive material (e.g.,magnetic receptive sheet) 29 covering at least a portion of at least oneface of the substructure 28, or the entire face, and at least oneexterior sheet 30 that covers the magnetic receptive material andincludes an illustration on its exterior-facing surface. In oneembodiment, the panel includes magnetic receptive material (e.g.,magnetic receptive sheets) 29 covering at least a portion of each faceof the substructure 28, or both entire faces, and two exterior sheets 30that cover the magnetic receptive materials and include illustrations ontheir exterior-facing surfaces. In some embodiments, the exteriorsheet(s) may be constructed of a printed sticker, printed cardstock, avinyl layer printed onto magnetically receptive material, wood veneerwith illustrations heat transferred, painted, etc. onto the surface, orother suitable materials known to those of skill in the art.

In some embodiments, a panel is constructed with a substructure thatincludes at least one magnetic edge, as described herein, and at leastone magnetic receptive sheet covering one face of the substructure (aportion of the face or the entire face) and including an illustration onthe exterior-facing surface of the magnetic receptive sheet, which formsan exterior face of the panel. In one embodiment, the panel includes twomagnetic receptive sheets each covering one face of the substructure(each magnetic receptive sheet covering a portion of one face or oneentire face of the substructure) and including illustrations on bothexterior-facing surfaces of the magnetic receptive sheets, forming thetwo exterior faces of the panel.

In some embodiments, a panel is constructed of magnetic receptivematerial, with at least one magnetic edge, as described herein, and anillustration on at least one exterior face of the panel. In oneembodiment, the panel contains illustrations on both exterior faces ofthe panel.

Dimensions of the panels of the construction toys described hereinshould be appropriate for use by the age range of children or otherindividuals who will be using the toy. For example, panel dimensionsshould be suitable to allow a user (e.g., a child) to pick panels up andmanipulate them with their hands.

Panels may be stored or carried in a sandwiched configuration, withfaces parallel or substantially parallel to each other and boundtogether by magnetic attraction at magnetic edges. When sandwiched, themagnetic attraction between panels may make it challenging to pull thepanels apart to initiate play, particularly for small children orindividuals impaired in certain motor skills. In some embodiments, aspacer is provided in the form of a ridge or gap between panels, whichfacilitates pulling sandwiched panels apart. Spacers may be configuredto provide finger hold leverage and/or to reduce panel-to-panel magneticattraction when panels are sandwiched face-to-face, by increasing thedistance between the edge magnets. In some embodiments, spacers areconfigured such that magnetic attraction between sandwiched panels isreduced to a degree sufficient to facilitate pulling the panels apart,while preserving sufficient magnetic attraction between panel edges foruse as a construction toy as described herein, e.g., sufficientattraction between magnetic edges to hold a three dimensional structureand/or scenery backdrop together. In some embodiments, panels maycontain a bevel on at least a portion of at least one edge, as shownschematically in FIG. 8. A gap 27 between the edges allows insertion ofa finger between panel edges and/or decreases magnetic attractionbetween magnets in adjacent magnetic edges in the stack of panels, tofacilitate pulling the panels apart. In other embodiments, panels maycontain a recessed area on at least a portion of at least one edgeand/or on at least a portion of at least one face. In other embodiments,panels may contain at least one ridge on at least a portion of at leastone edge and/or at least a portion of at least one face. In any of thesenonlimiting examples, a gap or space is created between adjacent panelsin a stack, making it easier to pull the stacked panels apart.

In some embodiments, a handle may be provided for ease of carryingpanels that are stacked together with their faces parallel orsubstantially parallel to each other and bound together by magneticattraction at magnetic edges. For example, ends of one or more handle(s)may be fastened to the substructure(s) of one or more panel(s) (e.g.,with a central portion of a handle protruding through openings in anedge of a panel). In another example, handle(s) may contain magnetic ormagnetically receptive material at the ends, which may attach bymagnetic attraction to one or more edge(s) or face(s) of one or morepanel(s) (e.g., as an accessory). The handle protrudes from the stack ofpanels, thus facilitating carrying a stack of panels as a group from onelocation to another. A handle may be made of any suitable material thatis capable of supporting the weight of a desired stack of panels. Forexample, materials that may be suitable for construction of a handleinclude, but are not limited to, ribbon, cloth, rope, fabric, leather,plastic, wood, or metal chain.

Magnets

The construction toys described herein include panels that contain atleast one magnetic edge. In some embodiments, more than one edge ismagnetic. In further embodiments, all edges of a panel are magnetic. Amagnetic edge includes at least one magnet embedded within proximity ofthe edge and oriented to magnetically attract a magnet embedded withinproximity of the edge of another panel, such that the panel edgesconnect by magnetic attraction when they are brought into contact. Insome embodiments, the magnets are configured such that the edges mayundergo a magnetic attraction only when panels are contacted with aspecific edge orientation, but preferably, the magnets are arranged suchthat panels may connect at any edge orientation. Exemplary, but notlimiting, possibilities for magnet configurations that do not limit theorientation at which the panels may connect include use of two dual polemagnets or one or more multipole magnet per magnetic edge, as describedin more detail below. “Dual pole” magnet refers to a magnet thatcontains one pair of magnetic poles. A nonlimiting example of a dualpole magnet is shown in FIG. 3. “Multipole” magnet refers to a magnetthat contains more than one pair of magnetic poles. A nonlimitingexample of a multipole magnet is shown in FIG. 4.

Typically magnets are embedded at a depth within the panels that is atclose proximity to a panel edge, such that magnetic panel edges willmagnetically attract each other when they are brought into closecontact. A suitable depth for magnets within the panel edge may bedependent on factors such as the strength of the magnets and the type ofmaterial in which they are embedded. For example, the magnets should beembedded at a depth such that when two panels are connected by magneticattraction at their respective magnetic edges and held or suspended withpanel faces in a vertical orientation and with the connected magneticedges at an intermediate position between the top panel and the bottompanel, the bottom panel will remain magnetically attached to the toppanel. In one embodiment, magnets are embedded at a depth of ≦1 mm fromthe panel edge.

In some embodiments, a magnetic edge contains an even number of dualpole magnets (e.g., 2, 4, etc.) disposed in alternating magneticorientation along the edge, and in alternating orientation around thepanel if more than one edge is magnetic. A nonlimiting example of a dualpole magnet is shown in FIG. 3. The example shown in FIG. 3 is a blockmagnet 9 with two poles (“N”) and (“S), with the magnetized direction Sto N shown with an arrow. The block magnet has a length 10, a width 11,and a thickness 12, and magnetized direction through the width. Oneembodiment of a panel edge is shown schematically in FIG. 5 with twodual pole block magnets 18, 19 embedded in an edge of a panel. Eachblock magnet is oriented with its length L_(m) parallel or substantiallyparallel to the edge of the panel and its width perpendicular orsubstantially perpendicular to the face of the panel, embedded to adepth of at least its thickness in the edge of the panel, and orientedwith a magnetized direction S to N (shown by arrows) through the widthand perpendicular to the length of the magnet, with magnets configuredin alternating S to N magnetic orientation along the panel edge. In anembodiment in which all edges of the panel contain dual pole magnets,the magnets are configured with an even number of magnets per edge andin alternating magnetic orientation around the edges of the panel.

In one embodiment, shown in FIG. 5, two dual pole block magnets 18 and19 are configured in opposite, alternating magnetic orientation(indicated by arrows showing the magnetized directions through themagnets) on the edge of the panel. In some embodiments, the dual polemagnets are spaced symmetrically and/or a constant distance apart oneach edge of a panel, or on each magnetic edge of the panels of theconstruction toy. For example, as shown in FIG. 5, where the totallength of the panel edge is represented by L, the length of each magnetis L_(m), the distance between magnets 18 and 19 is L_(s), and thedistance from each corner to the nearest magnet is L_(c),L=2L_(c)+2L_(m)+L_(s). A “corner” herein refers to the junction betweentwo edges of a panel. In some embodiments, all magnetic edges within agroup of panels contain dual pole magnets in alternating magneticorientation and symmetrically configured on the edge, with L_(c), L_(m),and L_(s) the same on each magnetic edge. In some embodiments, all edgesof a panel are magnetic edges that contain dual pole magnets inalternating magnetic orientation and symmetrically configured on alledges, and in alternating magnetic orientation around the panel, withall L_(c), all L_(m), and all L_(s) lengths the same around the panel.In some embodiments, all magnetic edges within a group of panels containdual pole magnets in alternating magnetic orientation with L_(s) thesame on each magnetic edge, and L_(m) and L_(c) lengths the same ordifferent. In some embodiments, all edges of a panel are magnetic edgesthat contain dual pole magnets in alternating magnetic orientation, andin alternating magnetic orientation around the panel, with L_(s) thesame on each magnetic edge, and L_(m) and L_(c) lengths the same ordifferent. In some embodiments, all magnetic edges within a group ofpanels contain dual pole magnets in alternating magnetic orientationwith L_(m) and L_(s) the same on each magnetic edge, and L_(c) lengthsthe same or different. In some embodiments, all edges of a panel aremagnetic edges that contain dual pole magnets in alternating magneticorientation, and in alternating magnetic orientation around the panel,with L_(m) and L_(s) the same on each magnetic edge, and L_(c) lengthsthe same or different.

In some embodiments, a magnetic edge contains at least one multipolemagnet that contains adjacent pairs of magnetic poles of oppositepolarity, where the number of poles is equal to 4n and n is an integer≧1, with the magnet configured along the edge of the panel such thatmagnetized directions through each pair of poles are oriented withalternating polarity. A nonlimiting embodiment of a multipole magnet isshown in FIG. 4. The multipole block magnet depicted in FIG. 4 containstwo pairs of poles (four poles, i.e., n=1) in alternating magneticpolarity. The multipole magnet has a length 15, a width 16, and athickness 17, and alternating magnetized directions through the width.Two pairs of poles 14 are configured in alternating magnetic polarity Sto N, indicated by arrows.

Where more than one multipole magnet is embedded in an edge of a panelor where more than one edge of a panel contains the multipole magnetswith pairs of magnetic poles of opposite polarity, where the number ofpoles is equal to 4n and n is an integer ≧1, the magnets are disposedalong the edge or around the panel in the same orientation of polarity.This is shown schematically in FIG. 7.

In one embodiment, shown in FIG. 6, one multipole block magnet with 4nmagnetic poles in pairs of poles of opposite polarity, where n is aninteger ≧1, is configured on the edge of a panel. In other embodiments,more than one of the multipole magnets may be configured on the edge ofa panel, with the multipole magnets configured in the same magneticorientation. In embodiments in which the multipole magnets are on eachedge of a panel, they are configured in the same magnetic orientationaround the panel. For example, FIG. 7 shows magnetic edges with two ofthe multipole magnets (e.g., 20 and 21) configured on a panel edge inthe same magnetic orientation, and in the same orientation around thepanel. In the embodiments depicted in FIGS. 6 and 7, a multipole magnetis configured with its length parallel or substantially parallel to theedge of the panel, with its width perpendicular or substantiallyperpendicular to the face of the panel and embedded to a depth of atleast its thickness in the edge of the panel. The magnet contains pairsof poles disposed along the length of the magnet with alternatingmagnetized directions through the width of the magnet and perpendicularto its length.

In some embodiments, the multipole magnet(s) with 4n magnetic poles inpairs of poles of opposite magnetic polarity, where n is an integer ≧1,are spaced symmetrically and/or a constant distance apart on each edgeof a panel, or on each magnetic edge of the panels of the constructiontoy. For example, where the total length of the panel edge isrepresented by L, the length of each magnet is L_(m), the distancebetween magnets on a panel edge is L_(s), and the distance from eachcorner to the nearest magnet is L_(c), L=2L_(c)+nL_(m)+(n−1)L_(s), wheren is the number of magnets on the panel edge. In some embodiments, allmagnetic edges within a group of panels contain the multipole magnetssymmetrically configured on the edge, with L_(c), L_(m), and L_(s) thesame on each magnetic edge. In some embodiments, all edges of a panelare magnetic edges that contain the multipole magnets symmetricallyconfigured on all edges with all L_(c), all L_(m), and all L_(s) lengthsthe same around the panel, and with the magnets in the same magneticorientation around the panel. In some embodiments, all magnetic edgeswithin a group of panels contain the multipole magnets with L_(s) thesame on each magnetic edge, and L_(m) and L_(c) lengths the same ordifferent. In some embodiments, all edges of a panel are magnetic edgesthat contain the multipole magnets with L_(m) the same on each magneticedge, and L_(m) and L_(c) lengths the same or different, and with themagnets configured in the same magnetic orientation around the panel. Insome embodiments, all magnetic edges within a group of panels containsthe multipole magnets with L_(m) the same. In some embodiments, allmagnetic edges within a group of panels contain the multipole magnetswith L_(m) the same and L_(s) and L_(c) lengths the same or different.In some embodiments, all edges of a panel are magnetic edges thatcontain the multipole magnets with L_(m) the same and L_(s) and L_(c)lengths the same or different, and with the magnets configured in thesame magnetic orientation around the panel.

In some embodiments, a magnetic edge contains an even number ofmultipole magnets (e.g., multipole block magnets) that each contains anodd number of pairs of poles of opposite polarity. Each magnet isoriented along the edge of the panel with alternating magnetizeddirections through the pairs of poles and perpendicular to the paneledge, and the magnets are configured with alternating orientation ofpolarity with respect to one another along the panel edge. The multipolemagnets may be configured with their lengths parallel or substantiallyparallel to the edge of the panel, with their widths perpendicular orsubstantially perpendicular to the face of the panel, and embedded todepths of at least their thicknesses in the edge of the panel. Eachmagnet contains an odd number of pairs of poles disposed along thelength of the magnet with alternating magnetized directions through thewidth of the magnet and perpendicular to its length. In someembodiments, an even number of the multipole magnets is spacedsymmetrically and/or a constant distance apart on each edge of a panel,or on each magnetic edge of the panels of the construction toy, with themultipole magnets disposed around a panel in alternating orientation ofpolarity.
